[cisco-voip] Outbound calls failing 0x80D2 - Identified channel does not exist

[MILLS, Mark]

Hi,

Thanks for this... It seems that despite originally being told we are
delivered 30 channels on the PRI's here by our telco guys, we infact
only receive 20.

I have done the busying out of the last channels as in the info below
and that has resolved the problem.. Thanks.

Thanks everyone for their suggestions and help!

Cheers,
  Mark
